Why it's important to use VPN?

The Internet has become a vital part of our everyday lives; we keep our information, our media, our property in a supposedly “safe” place.
So what happens when our private data’s security is compromised? Or when strangers can access all that we keep sealed and locked?

It is clear that you need to have your own security network. You need to have a VPN.
A technology that allows you to generate a connection between two or more computers or servers through another network is called VPN (Virtual Private Network).
Using encryption and cryptography makes the security level in the core network irrelevant, allowing you to use even public Internet for the connection.

Having a VPN makes your life much easier: You can keep your activity online to yourself, protecting yourself from any prying eyes. You can connect to any public WiFi network without being vulnerable to various hackers trying to steal your information. You can access worldwide content, withdrawing any boundaries that might have been established on your network’s location! And the list goes on and on…

Not having a VPN in the 21st century is pretty much like storing all of your valued possessions in the street, where anyone can take possession of it.

When I managed to work it all out, I started taking some pretty spectacular images. In this post, I will share with you everything that I’ve learned from my mistakes. A black and white photo of four beginners photographers holding DSLR cameras Infographic As beginner photographers, we tend to be visual learners. And it’s my job to make beginning photography as easy as possible for you. So I thought to myself, “What better way to help beginner photographers learn how to use their cameras, than by creating an infographic?” And that’s exactly what I did. I collaborated with an illustrator friend of mine, and together we made these images. The following are something that will make understanding exposure, and how cameras work, a whole lot easier! Check out what we came up with below: An infographic showing the basic functions of a camera - beginners guide to photography Let’s dive into more depth… Exposure For those beginning photography, exposure is key to capturing a great image. Learning how exposure works will help you to take control of your camera and take better photos. Aperture, shutter speed, ISO are the elements that combine to create an exposure. As you’ll soon learn, these elements have an effect on more than just the exposure. They also cause alterations in depth of field, motion blur, and digital noise. Once you understand how each one works, you can start diving into manual mode. This is where you take control back from your camera. The exposure triangle is a great way to remember the three settings. When combined, they control the amount of light captured from any given scene. This will help you to understand that changing one setting will necessitate a change in the others. That is if you are photographing the same scene with the same exact lighting conditions. Read here for all the information you need on the exposure triangle. Diagram explaining the exposure triangle - iso, shutter speed and aperture Aperture Exposure happens in three steps. We will start with the aperture. This is the hole inside the lens, through which the light passes. It’s similar to the pupil of your eye: the wider the aperture, the more light is allowed in and vice versa. Simple? Not quite. As the aperture widens, the f/number gets lower and more light is allowed into the camera. This is great for low light but be aware that it’s going to make the depth of field very shallow – not ideal when taking landscapes. So there’s a bit of give and take and I go into full detail about that in this post. The aperture is the preferred setting to set first, as it directly influences how much of your scene is in focus. But, if you are looking to create motion blur, then it is second to the shutter speed. Exposure will be much easier if you can memorize the f/stop scale. The scale is as follows: f/1.4, f/2, f/2.8, f/4, f/5.6, f/8, f/11, f/16, f/22. Digram showing the the f/stop scale for better understanding of photography for beginners Shutter Speed Once the light has passed through the aperture of the lens, it reaches the shutter. Now you need to decide how much of that light you’re going to allow into the camera. Ordinarily, you only want a very small fraction of a second (for example 1/250) to prevent motion blur. However, different shutter speeds complement different situations. Anything from really fast (1/4000) for sports photography to really slow (30 seconds) for night photography. It all depends on what you’re shooting and how much light you have available to you. Knowing how your shutter speed works is a key element in the basics of photography. A conceptual portrait of a girl in her bedroom surrounded by flying books - ISO Once the light has passed through the aperture and been filtered by the shutter speed, it reaches the sensor. This is where we decide how to set the ISO. As you turn the ISO number up, you increase the exposure. But, at the same time, the image quality decreases. There will be more digital noise or “grain”. So you have to decide upon your priorities in terms of exposure vs grain. For example, I would reduce the image quality if it meant that I could prevent motion blur in my photo. There’s no possible way to fix that in post-production (yet, at least). Aa atmospheric shot of an underground tunnel - digital photography for beginners Exposure Summary Once you’ve understood aperture, shutter speed and ISO, you need to learn how each of these elements of exposure work together. For all those basics of photography, exposure is the most important. If you don’t have this down, composition and framing become a moot point in beginner photography. In this post, you will learn about the ‘stop’ based system for measuring exposure. But, more importantly, how to prioritize the aperture, shutter speed, and ISO for the best photo. Every time. The corridor of an abandoned building taken during an urban exploration photography trip Understanding Your Camera Metering Modes Digital photography for beginners can be confusing. Exposure isn’t as simple as learning about aperture, shutter speed, and ISO. You also have to learn about how your camera looks at light. Metering modes are there to tell your camera how you want it to look at a scene. The photo below was taken on spot metering mode but, if you were to take the same photo using evaluative mode, you would end up with a completely different exposure. This is also covered in my free video training. If you’re looking for an article that explains digital, including Canon, metering modes, here it is. Understanding this basic photography point may just be the key to understanding why your photos are coming out underexposed or overexposed. A pristine winter landscape scene - dslr photography for beginners Histograms The histogram shows you a mathematical review of an exposure after the photo has been taken. It essentially tells you how evenly exposed a photo is. LCD screens aren’t very good at showing you this information through their display of the image. This is because they are affected by the ambient lighting conditions you’re in and the brightness of the screen itself. That’s why the histogram is such a powerful tool to utilize in beginning photography correctly. Screenshot of a photography histogram Shooting Modes Full-Auto, Program, Aperture Priority, Shutter Speed Priority or Manual Mode. How do you work out which one you should be using? There’s also a lot of misconceptions about which mode to use under which conditions. On top of a lot of bias towards not using manual mode. When you understand what exactly each mode does, the one that will be suitable for your situation becomes a lot clearer. This is also covered in my free video training. Portrait of a man onstage during a performance, atmospheric purple light behind -understanding shooting modes for photography beginners Depth of Field When you’re shooting in low light, you invariably have to widen your aperture to allow enough light into the lens. But this has one rather a major side effect. A shallow depth of field. This can be used very creatively (often to excess) but it’s not the only possibility. There are many situations, such as landscapes, where you’ll want to be using a narrower aperture so that the whole scene remains in focus. This tutorial walks you through everything you need to know about choosing the right aperture (and therefore the depth of field) for the right situation. When it comes to covering all of the basics of photography, depth of field is very important. A person holding a dslr camera to take a street photo - beginner photography tips White Balance White balance is something I wish I’d learned more about much sooner than I did. I look back on some photos now and wonder what I was thinking. The white balance changes the color cast of the entire photo. It is responsible for the overall warmth. It can determine whether your photo appears blue or orange, cold or warm. Auto white balance doesn’t tend to do a particularly good job, particularly with tungsten light. The sooner you learn about this basic photography idea, the more accurate your photos will look. This is also covered in my free video training. Bright and colourful outdoor travel photography portrait, demonstrating use of contrasting colors for photography beginners Focal Length Have you ever wondered what the ‘mm’ on your lens actually means? Or why people use longer focal lengths for portraits? It’s all discussed in this tutorial. The focal length affects more than just the ‘zoom’. It also influences the perspective. I cover which focal length you would want to use in different situations. As well as their possible side effects. It’s a really worthy read and one of my favorite tutorials to date. A diagram explaining how focal length works Crop Factor A lot of you may not realize but, unless you spend about $2000 on your camera, you’re more than likely to be shooting on a crop sensor. This means that your sensor is much smaller than professional SLR cameras, essentially cropping your image. The crop factor has a range of effects on your photos. It creates a narrower viewing angle and will influence your lens purchases in the future. For those beginner photographers, research what lenses will help your field of photography first.
